Rootstock digitate, somewhat tuber-like when fresh, ca. 3.5 cm long, thickened to ca. 5 mm in diameter. Stems solitary, simple or branched distally, 5–50 cm tall, proximally sparsely retrosely and somewhat spreading white puberulent, subglabrous or very sparsely spreading puberulent elsewhere. Basal and proximal leaves more or less rosulate, long petiolate; petioles 5–12 cm long, proximally sparsely somewhat spreading white puberulent; blades sparsely puberulent with very short appressed hairs on adaxial surface, sparsely puberulent with longer hairs along veins on abaxial surface and along margins, orbicular-reniform or orbicular-pentagonal, 2–6.5 cm long, 2.5–6.5 cm broad, deeply 5-lobed, lobes further divided into narrowly oblong segments 1–4 mm broad, obtuse or acute; cauline leaves few to several, petiolate; blades orbicular, finely dissected into linear or narrowly linear segments 1–3 mm broad or less. Inflorescence simple or compound racemes, rachis flexuous, very sparsely somewhat spreading puberulent or subglabrous, few- to several-flowered; proximal bracts leaflike, distal ones narrowly linear or subulate, ciliate; pedicels ascending to more or less divaricate, densely puberulent distally, subglabrous elsewhere; bracteoles borne in upper part of pedicels, subulate, 4–6.5 mm long, ciliate. Sepals deep blue or purplish, elliptic or obovate-elliptic, 1.1–1.8 cm long, appressed puberulent outside, spur subulate, straight or slightly curved upward, longer than sepals, 2–2.2 cm long. Petals glabrous, nearly rounded at apex. Staminodes blue, obovate, 2-lobed, ciliate, ventrally yellowish barbate; claws ca. 4.5 mm long. Stamens glabrous or sparsely puberulent. Carpels 3; ovaries densely puberulent. Follicles densely puberulent. Distribution and habitat :— Delphinium kamaonense is widely distributed in China ( Gansu , Qinghai , Sichuan , Xizang ), northwestern India , and Nepal ( Fig. 12 ). It often grows on open grassy slopes or in scrubs at altitudes of 2800–4800 m . Phenology :—Flowering from July to September; fruiting from September to October..

Notes :—In general aspect, Delphinium kamaonense is closely similar to D. yuanum Chen (1948: 176) , a species distributed in northwestern Yunnan , southwestern Sichuan (Daocheng, Xiangcheng) and southeastern Xizang (Zayu), China , but differs by having stems sparsely retrosely and somewhat spreading white puberulent proximally, subglabrous or very sparsely spreading puberulent elsewhere (vs. glabrous throughout), petioles basally spreading puberulent, subglabrous elsewhere (vs. glabrous throughout), inflorescence rachis very sparsely spreading puberulent or subglabrous (vs. glabrous), and pedicels densely puberulent apically, subglabrous elsewhere (vs. glabrous throughout). Notably, these two species have the same variation pattern in the division of basal leaves. Plants with less divided basal leaves and less laciniate leaf lobes in D. yuanum were also once described as an independent species, i.e. D. yanwaense Wang (1983: 157) , which was synonymized by Yuan & Yang (2015) .

FIGURE 12 . Distribution of Delphinium kamaonense (●). The arrow indicates the type locality of D. latilimbum , i.e. Cona county in southern Xizang, China. The color line illustration and the description given by Hunt (1978) , based on a plant collected from the Langtang Valley in Nepal and cultivated at Kew, for Delphinium caeruleum (“ coeruleum ”) Jacquemont ex Cambessèdes in Jacquemont (1844: 7) , actually refer to D. kamaonense . The former is also a widely distributed Sino-Himalayan species and largely sympatric with the latter. Morphologically D. kamaonense is readily distinguishable from D. caeruleum by have stems proximally and pedicels distally appressed puberulent, subglabrous or very sparsely spreading puberulent elsewhere (vs. stems and pedicels densely appressed throughout), flowers few in corymbs or solitary (vs. flowers few to several in simple or compound racemes), and 3 (vs. 5) carpels.
